Why do babies have the high amount of water?

Babies are composed of about 75-78% water at birth, which is significantly higher than the adult average of around 60%. This high water content is essential for their rapid growth and development, as water plays a critical role in various bodily functions, including temperature regulation, nutrient transport, and waste elimination. Additionally, since babies are still developing their organs and systems, maintaining adequate hydration is crucial for their overall health and well-being. As they grow, their water percentage gradually decreases.
